S ep 1 99 6 Repulsive particles on a two - dimensional lattice

Abstract

The problem of finding the minimum-energy configuration of particles on a lattice, subject to a generic short-ranged repulsive interaction, is studied analytically. The study is relevant to charge ordered states of interacting fermions, as described by the spinless Falicov–Kimball model. For a range of particle density including the half-filled case, it is… (More)
